Req. 5.3.5.3: "Alert Telemetry"

The FSW shall send alert telemetry messages, as defined in [9], to the SC via the CTDB. Alert telemetry is generated internally by the LAT and sent to the SC to be downlinked immediately. If not in contact, the SC recognizes the telemetry as Alert and activates a TDRSS link for immediate downlink.

Test(s)

003: Narrowband Telemetry Verification

This test shall verify the successful collection, sampling rate, formatting, downlinking, and transformation into user units of housekeeping and low-rate science data, alert telemetry, and diagnostic telemetry. If telemetry content is specific to a particular mode (i.e., boot mode or standard operation mode), this test shall verify the correct content as a function of mode.

016: LAT Performance Monitoring and Operations

This test shall verify that the FSW operates properly in every Science Mode, monitoring event data for integrity, tracking changes in event and detector statistics, and generating a report of any detected anomalies.
